Karst hydrogeology of the Kas-Kalkan springs along the Mediterranean coastof Turkey

The present studies were carried out along the southern Mediterranean coast of Turkey, where most of the karst springs discharge from highly karstifie d carbonate rocks. The case-study was applied in the Kas-Kalkan karst regio n, considered one of the most important touristic Mediterranean provinces i n southern Turkey. The purpose of this study is to identify the main water resources of the karst springs in the inland side and the expected groundwa ter flow paths that may recharge the coastal springs in the study area. A c omparison of the physiochemical properties and isotopic contents of the kar st springs along the Kas-Kalkan coastline is also considered an important t ool for identifying the hydrogeological characteristics and responses of th e different units in the study area. Relevant studies were carried out also considering the morphological and structural characteristics of these kars t springs and changes in their discharge amounts during the dry and wet per iods.
